It's now a year later and a lot has happened. Digital Disruption will soon be available as a hardback book (also as an eBook, natch). You can pre-order a copy now at Forr.com/DDbook. To complete the book I had to get far outside of my comfort zone -- I work with media companies and consumer product companies primarily, but to prove that digital disruption is a fundamental change in the way we all do business, I had to interview people in the pharmaceutical industry, the military camouflage industry, and I even recently spoke to the CIO of a cement manufacturer! And to my pleasant surprise, they were every bit as digitally disruptive as their counterparts in the consumer-facing enterprises that we think of when we imagine digital disruption.

One of the main reasons every company can be and eventually must be a digital disruptor is the rise of digital platforms. These platforms are founded on a set of devices, wrapped together with software experiences that identify each customer individually, and are open to app contributions from thousands of partners. The platform owners that matter today are Amazon, Apple, Facebook, Google, and Microsoft.
